H-Drol vs. Superdrol

Superdrol is way more harsh, but gives most people more results. H-Drol is generally considered more mild, with more mild effects. I'd advise searching around more, there's all kinds of useful info out there, just search for "m drol" or "superdrol" or "h drol" or "halodrol". You'll find plenty of useful threads.

These two threads are a good place for you to start (both complements of thesinner ):
